Abstract

The invention discloses acrylic acid low-temperature drying cathode electrophoretic paint and a preparation method thereof. The raw materials comprise the following components in parts by weight: 110-130 parts of propylene glycol monomethyl ether, 115-135 parts of propylene glycol ethyl ether, 115-135 parts of propylene glycol propyl ether, 140-160 parts of propylene glycol butyl ether; 10-30 parts of butadiene, 215-235 parts of methyl acrylate, 290-310 parts of 1-ethyl acrylate, 15-35 parts of 2-ethyl acrylate, 40-60 parts of 1-ethylene glycol monobutyl ether, 4-8 parts of 2-ethylene glycol monobutyl ether, 45-65 parts of 1-isopropanol, 15-35 parts of 2-isopropanol, 70-90 parts of a curing agent, 20-40 parts of monobutyl ether, 35-55 parts of butanone, 5-9 parts of a neutralizer and 38-58parts of pure water; wherein the curing agent is micromolecular resin, and the neutralizer is lactic acid, butadiene, methyl acrylate and ethyl acrylate which serve as monomer materials. According tothe acrylic acid low-temperature drying cathode electrophoretic paint and the preparation method thereof, compared with the prior art, the acrylic acid low-temperature drying cathode electrophoreticpaint adopting the technical formula has the advantages of good weather resistance, long salt spray time, good leveling property and low drying temperature.

Description

technical field [0001] The invention relates to the technical field of electrophoretic paint, in particular to an acrylic low-temperature drying cathodic electrophoretic paint and a preparation method thereof. Background technique [0002] Electrophoretic paint, also called electrophoretic paint, and many people still use the name "electrophoretic paint" instead of "electrophoretic paint". Electrophoresis is becoming more and more popular as the pitfalls of conventional spraying continue to surface. Electrophoretic paint has also begun to be continuously updated, from anodic electrophoretic paint to cathodic electrophoretic paint, from single-component electrophoretic paint to two-component electrophoretic paint, the development of electrophoretic paint has also promoted the development of electrophoretic coating, so that more products are no longer Instead of using spray technology, electrophoresis is used. Acrylic low-temperature drying cathodic electrophoretic paint is ...
